So were on the chapter where we factor polynomials by reversing the process and using zero factor property. Here are the questions with my answers...can someone check for me??
1. 12x^2=8x
12x^2-8x=0
4x(3x-2)=0
ANSWER= x=0 x=2/3
2. x(3x-2)-7(3x-2)=0
(x-7)(3x-2)=0
x-7=0 3x-2=0
ANSWER= x=7 x=2/3
3. x(x+9)=2(x+9)
x(x+9)-2(x+9)=0
(x-2)(x+9)=0
ANSWER= x=2 x=-9
Did I do these correct?
